A Dielectric Resonator loaded Substrate integrated waveguide cavity backed slot antenna (SIDRA) is proposed for two slot polarizations and orientation. A SIW-fed cylindrical DRA using rectangular slot is used for obtaining bandwidth of about 5% at 6.15 GHz. For enhancing bandwidth, a plus shaped slot with bandwidth of about 8.80% and gain of 3.7 dB is proposed. The proposed antenna represents S...

This thesis presents design of dielectric resonator loaded antenna for wireless applications. The design is a Different shape Dielectric Resonator Antenna (DRA) using different material for wireless applications. Here the DRA is excited by conformal patch connected to co-axial feeding which is an effective feed mechanism and more efficient in energy coupling than other types of feeding techniqu...

Several wideband antennas are presented for either wireless application. This paper presents the performance of a simple monopole antenna loaded with an annular dielectric resonator as a wideband transmitting/receiving antenna. By adjusting the length of the monopole and load arm, a 10-dB bandwidth of 94% is achieved while maintaining monopole-like radiation pattern, which covers UWB applicatio...

A rectangular pyramidal horn antenna fabricated with tapered dielectric E-plane boundary walls whose inner surface is periodically loaded with thin conducting strips is investigated. For better impedance matching, at the throat region of the horn antenna, 3 cm portion is metallised. The radiation characteristics of this horn antenna are compared with that of an identical conventional horn anten...

Three-dimensional information of the burden surface in high temperature and excessive dust industrial conditions has been previously hard to obtain. This paper presents a novel microstrip-fed dielectric-filled waveguide antenna element which is resistant to dust and high temperatures. A novel microstrip-to-dielectric-loaded waveguide transition was developed. A cylinder and cuboid composite str...

This paper presents design and fabrication equilateral triangular parasitic patch microstrip antenna array with operating frequency at 2.42 GHz, for wireless communication systems. The Industry, Scientific and Medical (ISM) Band, unlicensed with the range 2.40 2.4835 GHz is used as the operation band. The maximum bandwidth can be achieved by controlling the distance between the patch antennas a...

A design study has been performed for a lightweight, cylindrical array antenna for a hostile-mortar-locating radar system. A mathematical model of the array was developed which permitted tradeoff studies to be made of various array parameters. Data computed using the model compared very well with experimental and other theoretical data. Critical components of the array were built and tested and...

Recently, research interest has increased in the design, development, and deployment of microstrip antenna agent systems for high-level inference and surveillance in a wireless sensor network (WSN). The proposed Antenna agent systems employ migrating codes to facilitate flexible application retasking, local processing, and calculating parameters. This provides extra flexibility, as well as new ...
